Step-by-step walkthrough

The complete route is still being worked out. Only the opening moves below passed the current checks; they do not establish a full solution. This candidate assumes a clamp opens when its paired bar leaves; confirm this behavior in the game.

Ring
An open ring can rotate. Align its opening with the connecting pin to release that connection. Rings fly away automatically once their connections and constraints are released.
Blocking pin
A fixed pin sitting on a ring's edge. It holds another ring in place, so its gap has to face this pin.Read the mechanism guide →
Latch
Holds a ring in place. A stick locks it, so release the stick first and then turn the matching ring.Read the mechanism guide →

Read this board before making a move

Ring
An open ring can rotate. Align its opening with the connecting pin to release that connection. Rings fly away automatically once their connections and constraints are released.
Blocking pin
A fixed pin sitting on a ring's edge. It holds another ring in place, so its gap has to face this pin.Read the mechanism guide →
Bomb Ring
Carries a timed bomb and can clear other rings. Deal with it before the countdown ends.Read the mechanism guide →
Closed ring
A closed ring has no opening. Release its blocking connections using the surrounding objects; the ring flies away automatically when it is free.Read the mechanism guide →

Frequently asked questions

Which board should I use for level 81?

This page has 9 distinct boards. The default A board has 15 rings and 18 blocking pins. Compare these features and the thumbnails before following its steps.

What do the numbers on the diagram mean?

They identify individual rings, not the operation order. A written step can also describe a bar or latch, so the step number is not always the ring number. Match the ring number named in the instruction with the diagram.

What should I check when I am stuck on level 81?

Check whether the ring is open or closed, whether a stop pin limits rotation and whether a latch is still locked by a bar. Repeated rotation does not remove a fixed obstruction. Compare the neighboring connections, then return to the step for the matching ring number.
